you can use sed search and replace to just print the match, you just have to put the pattern in parentheses, and then reference the match in the replace part with a \1

pwd | sed...

you seem to know some perl, so why are you leaving out the semi-colons?

As a general rule of thumb, you need one after pretty much everything.

Any variable in the shell comes into existence by your shell's startup scripts...

I would start there. Not sure about ksh, but in bash it would be /etc/bashrc....start there, and that file should...

off the top of my head, this should work:

machine=`echo $hostname | awk -F'-' '{print $1}'`
group=`echo $hostname | awk -F'-' '{print $2}'`
building=`echo $hostname | awk -F'-' '{print $3}' |...

From the output of:

# help set
...
-x Print commands and their arguments as they are executed.

so just put "set -x" at the top of the script before any other commands.

A much more...

Insert is not "-i". It's just "i". Do not confuse sed "commands" with command line options. The command line option "-i" means to edit the file in place (dangerous!) in most sed versions that have...

"next" in awk means "stop processing the current line, and move onto the next line, starting at the top".

Don't confuse "next" with "getline".

"~" (tilde) is for a regular expression...

What exactly do you mean by "open the script"?

Reading the script, or executing it?

You're welcome. I'm glad that I could assist.

using command substitution:

$(some command)

is NOT how you call non-awk commands from awk.

What you want to do can be achieved with a little awk magic....just awk.

I just wrote this amazing script.

Check it:
ls /some/directory

OR, for the long listing:
ls -l /some/directory

OR, for the current directory:
ls

ORRR, for a long listing of the current...

First off, you should post ALL of the code, not just a snippet of the until loop. Based on your post, I have no clue what "$line" is.

Second, please use the code box/tags for your code...thats the...

well, this type of situation can depend on several factors..

do the "sudoers" all have full permission? if so then just make the script owned and executable by root only

otherwise you could...

Whipped this up...fun stuff, i'll leave the output formatting up to you

i created a file with your top input:
$ cat file
PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE ...

for one thing, to get a list of files to loops through, it would have to be something like this:

for file in `ls -1 $InputDirectory/*.shp`;
do
something with $file
done

The way you had...

if [ '/usr/bin/egrep "$kky2" $FL2' ] ; then

this will always be true because it is just a single quoted string in a test bracket. A string is always true.

maybe try something like this:
...

From the grep man page:

-o, --only-matching
Show only the part of a matching line that matches PATTERN.


In the words of the Kool-Aid guy....Ohhh-Yeeeaah!

This is some straight up homework. No one in their right mind is making a username and password glenn/glenn.

I am a part time Linux instructor, and this is the type of stuff i would have my...

Just to clarify what ghostdog said...this "startswith" business is whats known as a "string method", and in string methods (there are many), it uses strings, not regular expressions.

The only way...

I don't think you can set "?"

For one thing, you do assignment without the "$", so even if you tried, it would be $ set ?=127
$ echo $?
0

However, it doesn't achieve the desired result, as...

Quick word about this, and this is true of Bash, so I'm not sure if it is true in ksh...

You would need to use the "=~" operator, not just "=" to use the regular expressions.

[[ "stuff" =~...

just curious, why would we need the "which" command?

if "clear" is in our path, then wouldn't this work:

alias c='clear'

if "clear" is not in our path, then it is not going to work either...

You dont need all the extra "echo" commands for one thing. Also, you need to use double quotes. The only time you should not use double quotes in the shell, are when yo uhave special characters that...

I always tell people that are new to Linux/UNIX to concentrate on learning the Shell language itself (including shell scripting).

The shell is one of the common denominators of Linux/UNIX flavors....

VAR=$(time dd if=/dev/zero of=/dev/sda1 bs=512 count=2048;sync)

What you were doing before was basically:

time <output of "dd" command>

which doesn't make sense because the syntax for "time"...
